I agree that “most” of the issues are unfounded when dealing with rain. That leaves room for “some”.
YMMV. Without a doubt the RDS on a handgun is going to be the way to go. For me, I don’t think the technology is there yet, if it’s definitely headed in the right direction. SIG has a prototype P320 that is getting there.
Irons never fail to work. Even if one flies off, we should still be able to make COM shots at a reasonable self defense distance. Dont get me wrong, I have a RMR on a pistol, but its not for self defense, that no dot panic was enough to change my mind.
